Economic feasibility of solar heat for large consumers

The economic feasibility (profitability) is defined as the maximum permitted price minus transport costs and cost of heat from the relevant source. To determine the economic feasibility of heat sources in combination with with heat demand, a number of assumptions have been made regarding investments for the decoupling of heat from each of the sources. All euros are annual; investments are discounted annually and on a net basis with the following parameters: • Investments area-bound network: return requirement 8%, term 30 years • Investments transport network (from heat source to areas/clusters): return requirement 12%, term 30 years. The return requirement is higher here due to a higher risk of low heat sales at the start of the project (it often happens that not all homes are connected to the transport pipeline at the start). • Investments in heat sources: return requirement 8%, duration 15 years No data is yet available for the municipality of Vijfheerenlanden, which has been part of the province of Utrecht since 1 January 2019.
